So I've been away with work for a week and came back to my landy I unlocked it but the boot wouldn't open and the engine wouldn't start, I then couldn't lock it using the fob and locked it using the key, I've sourced some jump cables and went back with my mate to jump start it, but when I unlocked and connected the batteries up the alarm went off and now I can't lock or unlock the car using the fob at all and it won't start, any suggestions, I've looked in the manual and can't find anything.
